SEWING-MACHINE TABLE.

SPECIFICATION forming part of Letters Patent No. 347,358, dated August17, 1886,

I Application filed November 5, 1884. Serial No. 147,215. (No model.)

To all whom it may concern.-

Be it known that I, ELIZABETH LAUFER, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Sewing-MachineTables, of which the followingis a specification, ret erence being hadtherein to the accompanying drawings.

My invention comprises a specific construction of coupling devices,wherewith an extension leaf'can be readily attached either to one end orto the rear edge of a sewing-machine table, the details of said devicesbeing hereinafter more fully described, and pointed out in the claim.

In the annexed drawings Figure 1 is a plan showing apair of my couplingdevices applied to an end and back leaf, said leaves being detached froma sewing machine table. Fig. 2 another plan, but showing said leavescoupled to the table. Fig. 3 is a plan of the under side of the endleaf. Fig. 4 is an enlarged elevation of thatend of the table to whichthe leaf is applied. Rig. 5 is an enlarged vertical sectionthrough aportion of the table and coupled leaf. Fig. 6 is an enlarged elevationof one of the keepers, a bearer being shown inserted therein andsectioned. Fig. 7 is a longitudinal section of said keeper, the bearerbeing pendent therefrom. Fig. 8 shows the manner of suspending the leaffrom the table.

A represents a sewing-machine table, and B is a leaf capable of beingapplied to the end of the same, the under side of said leaf havingbearers G O rigidly secured thereto, which bearers terminate with eyes 0c.

D D are keepers secured to the under side of table A, each keeper beingprovided with a vertical slot, E, horizontal slot F, socket G, andbridge H, as more clearly seen in Figs. 6 andi'.

I are screws or pins inserted in the under side of the table, for apurpose that will presently appear.

J is a secondary leaf, to be applied to the rear edge of the table, saidleaf having attached to it bearers K K, provided with eyes k k.

From this description it is evident the leaf B is readily attached tothe end of table A b5 simply inserting the eyes 0 0' in the horizon talslots F of the keepers D D, and then slid ing said leaf toward saidtable, care being taken to slightly elevate thefree edge of the former,so as to cause said eyes to engage ovei the screws or pins I. When thusapplied, these screws prevent the leaf being pulled away from the end ofthe table while the bridges H of the keepers sustain the weight of saidleaf, as will be more readily understood by referring to Fig. 5.Furthermore, the leaf cannot shift either toward the front or back ofthe table, because the hearers 0 0c cupy the vertical slots E of thekeepers, as seenin Fig. 6. To uncouple the leaf, its free edge is againslightly elevated to disengage the eyes 0 c from the pins I, and saidleaf is pulled out until said eyes reach the position seen in Fig. 7when the leaf may be allowed to hang from the table, as represented inFig. 8. In this pendent position of the leaf the eyes 0 c occupy thesockets G of keepers D, but when the leaf is to be bodily detached, itis advanced horizontally until said eyes pass completely through theslots F. Finally, it is evident the secondary'leaf J can be applied tothe rear edge of the table in a precisely similar manner, and, ifdesired, the former can extend the entire length of the latter, as

suggested by the dotted lines in Fig. 2.

I claim as my invention A coupling device for sewing-machine tables,which coupling consists of the bearers C 0, having eyes 0 c, and beingrigidly secured to the under side of detachable leaf B, in combinationwith the table A, provided on its under side with keepers D D andretaining devices I, each of said keepers being furnished with avertical slot, E, horizontal slot F, socket G, and bridge H, saidbearers being inserted in said vertical slots to prevent the leafshifting either toward the front or rear of the table, as hereindescribed.

In testimony whereof I affix my signature in presence of two witnesses.

ELIZABETH LAUFER.
